What is ComfyUI?

ComfyUI is a visual programming interface for building AI workflows using drag-and-drop nodes. Create sophisticated image, video, text, and audio generation workflows without coding. FlowScale AI deploys these workflows as production APIs.

​
Core Capabilities

ComfyUI workspace showing multiple connected node chains for text, image, and video processing with clear data flow between AI models

Beyond Images

Build complex workflows for images, videos, audio, and text generation—all in one interface

Complex Logic Made Simple

Create conditional workflows, multi-step pipelines, and advanced AI operations without coding

Drag-and-Drop Power

Each block (called a node) does one specialized job—combine them to build enterprise-grade GenAI solutions

Universal Compatibility

Works with any AI model, custom nodes, and runs anywhere—Windows, macOS, Linux, or cloud
Key features:
  • Visual Programming: Connect nodes instead of writing code
  • Multi-modal: Support for images, videos, audio, and text
  • Real-time Editing: Modify workflows and see results instantly
  • Community Extensions: Thousands of custom nodes available

​
Workflow Structure

Workflows consist of connected nodes that process data:
1

Input nodes

Load models and define prompts
2

Processing nodes

Apply samplers, upscalers, and transformations
3

Output nodes

Save or display results

Key Concepts

TermThink of it as…Why it matters
NodeA single LEGO® brickDoes one job (e.g., “Load model”)
WorkflowThe finished LEGO® setRuns the whole image pipeline. Saved as .json
Model / CheckpointA cookbookHolds all the AI knowledge—whether for images, text, video, or audio
Custom NodeA fan-made LEGO® pieceCommunity add-ons—try new ideas without waiting for official updates
Pod (FlowScale)A line cook in the cloudExecutes your workflow on a rented GPU

​
Basic Workflow Example

1

Load Model

Choose your AI model (SDXL for images, LLaMA for text, etc.)
2

Add Input

Enter your text prompt
3

Configure Processing

Set parameters like steps, strength, and sampling method
4

Process Output

Convert output to desired format
5

Save Results

Output saved to results folder

​
Essential Terms

Text that describes the image you want
The big file that stores the AI model’s brain
The method that slowly sharpens the noisy blob into a picture
A small add-on file that teaches the model a new style or character
A cloud worker that runs your workflow
